IMPROVEMENT IN SHAVINGS-SEPARATORS.

Specification forming part of Letters Patent N o. l 81,404, dated August 22, 1876; application filed July 31, 1876.

To all 'whom fit may concern:

Be it known that I, ELIJAH BROWN, in the city, county, andvState of New York, have invented a new and Improved Shavings-Separator, of which the following is a specication:

Figure 1 is a vertical section on line x in Fig. 2. Fig. 2 is a longitudinal section on line yy in Fig. l.

Similar letters of reference indicate correspondin g parts.

, The object of my invention 4is to separate the ner from the coarser shavings made in planing-mills and other wood-working ma' chines; and it consists of a screen hung in-an inclined position upon two sets ot' swinging arms, and provided with a divider or frame carrying a number of cross-wires a short distance above the screen. The screen is arranged to take motion from a crank driven by any convenient power, and the divider is arranged to move with the screen, but through a greater space, constantly shifting its position in relation to the screen.

A is a screen or sieve, which lis supported by a framing, B. C is a boxor chute, vformed around the screen, and left open at the lower end d. The side pieces a, forming part of the frame B, are allowed to project beyond the screen at each end, to receive the swinging arms D D', which are pivoted to the side pieces a, and to the hangers b o, or any other convenient support. The hangers b are longer than the hangers allowing Ythe screen to pitch downward, so that the'open end d is lowest. The swinging arms D are elongated,

and connected by joints e to the sides fg of the divider E, that slides a small distance above the screen. The endsof the rodsfg slide in the eyes h t'. Attached to the framing of the screen j are cross-bars, connecting the bars' f g.

F is a connecting-rod, that transmits motionfrom the crank Gr to the screen. The crank Gr may be moved by any convenient power.

The shavings are delivered to the upper end of the screen by the ordinary shavings-car vD than the screen, receive a greater motion than that ot' the screen, and thoroughly agitate the shavings, making the separation more complete.

Having thus described my invention, I claim,

as new and desire to secure by Letters Patvent- The combination of the screen A, swinging arms D D, pivoted to a suitable support, and

stantially as specified.
